Use windows path syntax when writing PDB module name.

Without this we would just append whatever the user
wrote on the command line, so if we're in C:\foo
and we run lld-link bar/baz.obj, we would write
C:\foo\bar/baz.obj in various places in the PDB.
MSVC linker does not do this, so we shouldn't either.
This fixes some differences in the diff test, so we
update the test as well.
